Be it known that we, ANTON MAYER and HENRY G. STIEBEL, citizens of theUnited States, residing at Cincinnati, Ohio, have in- 5 vented new anduseful Improvements in Sprinkling Apparatus,,of which the following is aspecification.

Our invention relates to improvements in street-sprinklers, its objectbeing to secure a 10 more uniform and economical distribution of waterwith reference especially to use in cities. To this end it consists inthe apparatus and mechanism hereinafter described, constituting anattachment to a wheeled supplydistributed by one or more rotatingbrushes driven by the bearing-wheels. By means of this rotation thewater is driven by centrifugal force in finely-divided particles in awidely-expanded horizontal shower covering the street-surface with greatuniformity and laying the dust much more effectively than is usual withsprinkling apparatus. With properly-constructed machines a pathcoversprinkled at one passage of the cart without interference withordinary traflic.

It also consists in certain minor features, in combination, tending tothe more complete and perfect operation, all as more fully and at largehereinafter described, and set forth in the claims. I

Mechanism embodying our invention is illustrated in the accompanyingdrawings, in

c Figure 1 is a rear elevation of a sprinklingcart to which ourinvention is applied; Fig. .1 2, a plan view of the rotatingdistributers and their casings detached from the tank;

our attachment. Fig. 4 is a plan view of one of the rotatingdistributors detached and upon a larger scale; Fig. 5, a detail verticalsection of the distributer-casing and distributor; Fig.

In the drawings,] designates the supply- V tank mounted upon a frameicarried upon the bearing-wheels 3 in the usual manner.

Serial No. 24 2,17 1. (No model) idesignates a standard provided with alateral arm 5, constituting a double-armed bracket secured to andsuspended from the under side of the frame 2 at the rear at one side ofthe wagon, and G 7 a similar standard 5 5 and arm occupying acorresponding position at the other side. Through the standards andtheir lateral arms is journaled 'a shaft 8, provided near one end with asprocket-wheel 9, driven from a similar sprocketewheel 10 upon the hubof the nearest bearing-wheel 3, thus rotating the shaft 8 as the wagonmoves. I

In the present illustration of our inventio we have shown a single shaftwith but one driving-gear; but in practice we may employ two shaftsextending in the same axial line between and in the arms of each of thebrackets with independent sprocket wheels and chains to oppositebearing-wheels, fora pur- 7o pose presently to be explained.

Each vertical arm, as 4, is hollow near the bottom, forming a socket inwhich is held 'a. short stud 11, extending downward through or to thebottom of the distributer-casing 12. 7 5 The arm 6 is similarly providedwith a stud 11, also extending down through or to the bottom of thecasing. These studs are held in the sockets byset-screws 1314, or in anyother eonvenient manner, and in turn uphold the So casing by bolts 1515, passed through the easing from below into the studs.

' The general form of the casing 12 is that of two flat half-cylindersmerging at their joined peripheries, constituting in effect two casingsseparated by a partition 16 at their junction.

In each division of the'casing thus formed is mounted a rotatingdistributor in the form of a circular brush, these being dcsignated bythe numbers ]7 18, carried respectively upon 0 sleeves 19 20 surroundingthe studs. These sleeves are provided respectively above the casing withbevel-gears 2 meshing with similar lwvel-gears )3 :24 upon the shaft 8,through which rotaiionis' given the distributers.

The constriuetion of the distributors is clearly indicated in Figs. 4and 5. Each con sists of two disks or hubs 25, between which andprojecting outward radially is secured a mo mass 26 of bristles, wires,or strips of any suitable material, of moderate stiffness. The relativepositions'of the distributers are indicated in Fig. 2, in which also therelative direction of rotation is indicated by arrows.

Water is distributed to the two distributers from the tank 1 throughseparate pipes or hose 27 28 controlled by suitable valves, so thateither or both may 'beshut OK when desired. Distribution through thecasings is made through somewhat enlarged orifices 29. 30, preferablycovered with wire netting, which assists in distributing the water moreuniformlyto the brushes of the distributors. These openings are locatedpreferably as shown, and distribute water to the brushes from above asthe bristles pass in'rotation below in the casing. The rotation of thebrushes drives the water radially outward by centrifugal force, modifiedas to the same by the tendency of the water to adhere to the bristles ina manner somewhat analogous to capillarity, and results in a horizontalexpanding shower of minute particles, which, as the wagon moves along,falls upon the ground evenly and gently. By the relative arrangement'ofthe rotating distributors and their supply-orifices 29 30 the twoshowers thus created practically merge at the line of junction withoutexcess at that point and thus cover an extraordinarily wide path. Thecentrifugal force thus obtained also enables us to place thedistributers at a very low level, so that the ordinary street-service iscarried on without reference to passing vehicles or horses.

The bevel-gears 23 24 upon the drivingshaft8 are normally loose uponsaid shaft, but are brought into engagement with it, when desired, byclutches 31 82, by suitable connections in control of the driver.connections are shown by the plan, Fig. 9.

In connection with the casing 12 we employ with each distributer anadjustable shield 33 34, formed to the arc of the outer wall of thecasing and arranged to slide and be adjusted rearward, as shown on theright in Fig. 2. The shield thus projected cuts off a given segment ofthe radial shower, as will be obvious, and is useful as a means ofprotection to passers-by, &c. The shields are guided and operated bymeans of pins 35, projecting upwardly from'cach through a curved slot inthe upper wallof the casing, to which suitable mechanism-such asmanipulating-rods (not shown in the drawings)mayjbe attached,

extending forward within control of the driver or attendant.

The clutch-' starting of the wheel and shut off simultaneously with thestoppage.

Where two such rotating distributors are employed as in the illustrationthe arrangement just described is an especial convenience in city usewhere street-traffic is going on during the sprinkling.

The foregoing description has reference to the use of two co-operatingdistributers, by-

which, generally, the best effects are obtained in ordinarystreet-service; but it will be seen that the action of each distributoris independent. Hence. but one maybe used, or any convenientnumberemploycd together, as in the illustration. lVe have also describedthe rotating brush as made up as radial strips-- such as bristles, wire,&c.but we may use porous material-such as sponge-cloth or the like-insuitable strips or masses to carry the water outward and distribute thesame in a finely-divided form.

We claim as our invention, and desire to secure by, Letters Patent ofthe United States- 1. In a street-sprinkler, the combination of awheeled reservoir, one or more circular brushes arranged to rotatehorizontally at the rear of thesame, driving-connections with thebearing-wheels and water-connections .with the reservoir, whereby theforward travel the casing, arranged and operating to dis-.

tribute the water horizontally in an expanding shower of finely-dividedparticles rearward and laterally across the path of the vehicle,substantially as set forth.

3. In a street-sprinkler, the combination, with the wheeled reservoirand its bearingwheels, a double casing carriedat the rear of thereservoir and having two independent adjacent semi-cylindricalcompartments open at the rear, two brushes revolving horizontally insaid compartments and through the rear openings, respectively, inopposite directions, and a branched supply-pipe from the reservoirentering the casings, respectively, and driving-connections with thewheels for the rotation of the distributors, substantially as set forth.

4. The combination, in a street-sprinkler,

of a semi-cylindrical casing to and through which water is distributed,a circular distributor or sprinkler mounted and rotated axially withinthe same, and one or more admechanism between said stop-cock and theclutch-actuating devices, whereby the movement of the clutch out ofaction closes the water-supply to the sprinkler, and vice versa,substantially as set forth.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
